MAX350CAP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX350CAP+ is a dual 4-channel serially controlled multiplexer housed in a 20-lead SSOP package. It operates on single supplies from +2.7V to +16V or dual supplies from ±2.7V to ±8V. The device features an on-resistance of 100Ω maximum, matched between switches to 16Ω maximum. It supports rail-to-rail analog signal handling and includes an asynchronous RESET input. The serial interface is compatible with SPI, QSPI, and MICROWIRE standards.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the operating voltage range matches the system requirements. Check for RoHS compliance status as indicated in the manufacturer's ordering information. Confirm the package type corresponds to the design layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-channel multiplexing solution is required with low-voltage operation. Consider the 100Ω on-resistance and 16Ω matching tolerance for signal integrity. Verify that the serial interface timing meets the controller's clock speed requirements. Evaluate the thermal dissipation capabilities within the SSOP package constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX349/MAX350 family of serially controlled multiplexers. The MAX350 variant specifically provides two independent 4-to-1 mux channels. It is designed for applications requiring flexible signal routing with minimal digital interface complexity. The device integrates shift registers for serial data input.
